Chromatic-achromatic perimetry in four clinic cases: Glaucoma and diabetes [PDF]

Indian Journal of Ophthalmology, 2015
Background: Some diseases that affect the visual system may show loss of chromatic-achromatic sensitivity before obvious physical signs appear in the usual examination of the eye′s posterior segment.

Visual Function Assessment in Geographic Atrophy: A Review. [PDF]

Clin Exp Ophthalmol
ABSTRACT Geographic atrophy (GA) causes significant vision impairment and reduction in vision‐related quality of life. Fundus autofluorescence (FAF) is the gold standard of structural assessment of GA but is a surrogate marker for vision loss, which can be assessed by tests of visual function and functional vision.

Bilateral Simultaneous Acute Angle-Closure Glaucoma Following Over-the-Counter Cold Medication. [PDF]

Case Rep Ophthalmol Med
Purpose We report a case of bilateral acute angle‐closure glaucoma occurring concurrently after the intake of dextromethorphan, a commonly used over‐the‐counter medication for flu symptom relief. Case Presentation A 65‐year‐old woman presented with bilateral acute angle‐closure glaucoma following 5 days of treatment with an OTC medication.

The Use of Combined Fundus Photography and Perimetry for the Assessment of Patients Referred for Intracranial Hypertension or Follow-Up of the Diagnosis in a Tertiary Headache Center. [PDF]

Eur J Neurol
ABSTRACT Objectives Idiopathic intracranial hypertension (IIH) is characterized by increased intracranial pressure and papilledema. If left untreated, it can lead to vision loss, and, timely detection of papilledema is of paramount importance. Direct ophthalmoscopy can be difficult to perform and interpret for non‐ophthalmologists.

Gaze-contingent flicker pupil perimetry detects scotomas in patients with cerebral visual impairments or glaucoma [PDF]

, 2018
The pupillary light reflex is weaker for stimuli presented inside as compared to outside absolute scotomas. Pupillograph perimetry could thus be an objective measure of impaired visual processing.

Comparison of threshold Saccadic Vector Optokinetic Perimetry (SVOP) and Standard Automated Perimetry (SAP) in glaucoma. Part II: patterns of visual field loss and acceptability [PDF]

, 2017
Purpose: We compared patterns of visual field loss detected by standard automated perimetry (SAP) to saccadic vector optokinetic perimetry (SVOP) and examined patient perceptions of each test.

Portable Perimetry Using Eye-Tracking on a Tablet Computer—A Feasibility Assessment [PDF]

, 2019
Purpose: Visual field (VF) examination by standard automated perimetry (SAP) is an important method of clinical assessment. However, the complexity of the test, and its use of bulky, expensive equipment makes it impractical for case-finding.
